WATER EJECTOR Patented Sept 13, 1938 UNlTED STATES PATENT ore-Ice WATER EJEGTOB Eugene M. Evans, Jefferson City, Mo.,' assignor of ten percent to Ernest LTietjen, Jefferson City, Moi 1 Application December 1 1 Claim.

it. operates to. direct steam in the form of an unbroken conical sheet, onto the column of water so that all portions of the column will be moved equally, thereby eliminating the agitation and other undesirable motion set up where the column of water is subjected to a broken or unevenlifting force.

-A further object is to provide water ejecting means which is adjustable readily for varying the volume of the expelling or lifting sheet of steam to meet the working requirements.

Another object is to provide an ejector the parts of which can be readily separated for the purpose of cleaning or repairing them.

Another object is to provide a structure capable of utilizing more than one conical sheet of steam for ejecting a column of water.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings Figure 1 is a central vertical section through the ejector. v

Figure 2 is a section on line 2-2, Figure 1.

Figure 3 is a section on line 3-3, Figure 1.

Figure-4 is a view similar to Figure 1 showing a modified construction.

Referring to the figures by characters of reference l designates the base of the ejector formed with a central screw-threaded head 2 from which extends a frusto-conical tip 3 constituting a valve member.

The body of the ejector has been indicated at 4 and has a screw-threaded-socket 5 for receiving the head 2, this socket opening into an annular chamber 6. A longitudinal passage 1 is provided in the body 4 and has one or more radial inlets 8 to which water is adapted to be supplied from any suitable source through pipes 9 or the like. A tapered port I!) extends from one end of passage I to the chamber 6 and is concentric with the tip 3. Thus by adjusting the head 2 within the threaded socket 5, the tip 3, which in a sense constitutes a 2, 1936, Serial no. 115,602 (Cl. 1oa.-2s4) valve, can be moved toward or from the wall of the opening l0, thereby to shut off communication .between chamber 6 and passage '1 or to produce an unbroken conical annular outlet of any desired area. 6

Formed on the body I is an exteriorly screwthreaded tip ll through which the passage 1 extends and the free end of this tip is tapered to form .a valve, as indicated at l2.

Screwed onto the tip II is a head i3 having 10 an extension H for receiving an outlet pipe i5 alining with the passage I. An opening I6 is formed in the head between the pipe and the passage and leading to this opening is a tapered port i'l corresponding in pitch with the end I2 5 of tip I i. This opening I! establishes communication between the opening it and an annular compartment 18 in head l3. The wall of opening I1 and the tapered surface l2 of the tip H cooperate to form an annular cone-like'passage 0 which is unobstructed and which serves todeliver steam in a conical sheet upwardly from compartment i2 into opening it,

A steam supply pipe l9 opens into the chamber I8 and a steam passage 20 extends from this chamber l8 to the chamber 6. Thus when steam is submitted from pipe i9 it will be distributed to both chambers 6 and I8 so that it can escape into passage 1 and pipe i5 through the conical outlet provided therefor.

In practice water or other liquid to be ejected is admitted to the device from pipe 9 and flows into the passage I and through opening 18 to the pipe l5. Where more than one pipe 9 is used, as

for example in Figures 1 and 3, the inflowing 35.

streams ofliquid will all enter the passage 1 as will be obvious. When steam is admitted to the device under pressure it will enter the two compartments 6 and i8 and then issue in the form of strong conical jets through the openings I0 40 and II. The sheets of steam thus escaping are unbroken because there is nothing in the openings to break up the sheets of steam passing therethrough. Therefore both conical sheets of steam will surround the column of water and impart an upward impulse thereto along lines extending continuously around-the column. As a result the column of water will be lifted and ejected more rapidly and efliciently than by any means wherein broken jets of steam are employed or a continuous annular jet is notused.

By adjusting the head 2 relative to the body 4 the thickness of the conical sheet of escaping steam can be increased 'or reduced thereby to increase or reduce its lifting power. Obviously by the head I! relative-to body 4 for the purpose of chamber 21.

varying the size of the jet escaping through the opening IT. This modification is so obvious that a detailed description or an illustration thereof is not deemed necessary.

It will be noted furthermore that it is not necessary to use an ejecting device utilizing two conical sheets of steam. Instead a single structure such as shown in Figure 4 could be employed. In this modified construction the base 2i has a screw-threaded head 22 with a conical tip 23. An inlet pipe 24 opens into the head 22 and through the tip 22, the passage 25 in the tip being concentric with the head as'shown.

The body 28 of the device is screwed onto the head 22 and has an annular chamber 21 and an opening or port .28, this port being tapered to correspond with the taper of the tip 23 and lead:- ing to an outlet 28 in communication withan outlet pipe 30. A steam supply pipe 3i opens into Obviously by adjusting the head 22 relative to the body 26 the space between the tip 23 and the wall opening 28 can be increased or reduced thereby to increase or reduce the thickness of the conical stream or sheet of steam escaping from chamber 21 into the outlet 29.

It will be noted that in both forms of the device illustrated the construction is very simple and tion to the use of steam. ll

What is claimed is:

An ejector including a base, a tapered screwthreaded tip thereon, a body having a tapered port adjustably engaged by said tip, a chamber in the body extending around and opening into 15 the port and having its communication with the port controlled by the tip; a tapered screwthreaded tip on the body. a fluid passage extending through said tip and its body, and past said port, a head adjustably seated on the tip on the body and having a tapered port, a chamber in the head in communication with the chamber in the body and having its communication with the port in the head controlled by the adjustable tip on the body, said chamber extending around and opening into said port, means for directing iiuid away from the port in the head. and means for directing a fluid under pressure into said chambers.
